Search everything with ⌘K

Press ⌘K and search the whole workspace in one window. It opens on your recent searches, by day; start typing, and messages, people, channels and pages come up with your words lit. Tab narrows the search to a channel or a person.

Filters narrow it further, a preview shows the message or the page with its cover before you open it, and a reply found in a thread opens that thread with the message centred and lit.
